RE: __Inspection of proposed building site at:

Dear Tom,
As requested, Branch Engineering inspected the building site on March 21, 1991. The building
site was undisdurbed,
By examining the cut areas near the street and utility areas, the foundation soil was found to to
be similar to other soils found on building lots nearby, which is a silty clay loam (dark brown)
with cobbles mixed with the soil. The Lane County Soil Survey indicates this soil as Type 43C
Dixonville- Philomath-Hazelair complex,
We recommend the following construction method be used at this site:
1. When the building pad area is excavated, the cut should be "stepped" or cut into the
existing ground to "key" the foundation in place, Do not dig "holes" that will trap water but
grade out poor material and slope gently to drain away to the north.
2, To provide an all-weather work area, crushed rock should be placed over the excavated
soil. Crushed rock and subgrade should be compacted when site has dried,
3, Perimeter 3" or 4" perforated pipe should be installed as a french drain along the south
walls of the structure (the east and west walls may also need perforated pipe as determined after
excavation), Slope pipe to drain to the north and run solid 3" or 4" pipe (also roof drains) to
outfall at curb/gutter weephole.

4. Add rebar to perimeter foundation, such as (1) continuous #4 bar at top of stem wall and
(2) continuous #4 bars at footing.
Based on the completion of the above construction methods, the site would be suitable for the
proposed residential structure,
If you have any questions, please call our office.
Sincerely,
